ATTACHMENT FOR CUTTING FELLIES OR THE LIKE.

SPECIFICATION forming part of Letters Patent No. 707,179, dated August19, 1902.

Application filed May 16,1902. Serial No. 107,632. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM E. SWINDELL, a citizen. of the UnitedStates,- residing.at

Moberly, in the county of Randolph and State I will proceed to describemy invention with reference to the accompanying dawings, in which-Figure 1 is a plan View of an attachment embodying my invention, thetable and a cor tain plate being partly broken away. Fig. 2 is avertical section of the attachment and the table, taken online at ofFig. 1, showing a portion of the saw. Fig. 3 is a transverse section ofthe pivot-arm and a part of the carrier, showing the pivot-bolt. Fig. 4.is a top plan View of thepivot-arm detached from the table. cutsrequired for a felly or the like.

Fig. 515 a diagramillnstrating the size, showing the stops for thecarrier. Fig.

7 is an enlarged isometrical view of oneof said stops.

1 designates a portion of a saw-table, and:

3is'the portion of the saw the table.

My attachment comprises a slotted arm 4 and a carrier-fram'e52l 12,mounted pivot-. ally on the arm, as presently described. The arm 4 issecured to the bottom of the table with bolts 6. The outer half 'of thearm has extra thickness, so that its upper face comes A longitudinalslot 7 is out in the projecting portion of the arm 4: to receive apivot-bolt 8. A washer v9 is secured permanently on said passingthroughv pivot-bolt and rests on the arm 4, thereby supporting. saidbolt. Belowsaid arm said bolt is provided with a wing-nut 14,bytightening which bolt 8 may be secured at any point along'th'e slot 7.x I I Thecarrier-frame or carrier 5 21 12 is constructed asfollows:Radialarms 5 12 13 have Fi 6' is a bottom planview of the table reducedinf their converging ends secured to a rectangular casting 15. One ofthe outer arms 5 is bent at 16, and its-outer endis secured to anarcpiece 17, made preferably of angle-iron. The arms 5 12 13 are alsoof-angle-iron. The divergent ends of the inner arms are secured to anarc-piece 1.8 and are further connected by arc-shaped stiffeners 19.

I Secured to the outer arc-piece 17 by rivets or screws are a pair ofbent guides 21, which are separated from each other by thick washers orcollars 22. Two guides 23 are held upon the bent guides 21 by bolts 24,passing between the latter. Guides 23 are slotted, as shown,

to permit of longitudinal adjustment thereof to determine the width ofthe fellies, &c.

Connected to the outer end of arm'12 by a hinge 26 is a gate 27, made ofa piece of angleiron. The purpose of this gate is to permit the saw 3 tobe inclosed within the gate 27, arc-pieces 17 and 18, andarm 5. Adrop-latch 28 is pivoted on the gate 27 and holds the gate closed byentering a notch in the upper edge of arc-piece 17. Any preferred latchfor the gate may be employed. v

, For supporting the pieces of stock to be cut a wooden plate 29 islaidupon the flanges of the arc-pieces 17 18 and of arm 5. A handleknob31 is secured to the arm 5 for actuating the carrier 5 21 12 whencutting stock, andthe plate 29 is cutaway, as shown, around said knob,so that it may easily be removed from the carrier and another platesubstituted for it, as aplurality of plates, like 29, are employed inmaking cuts of different curvatures. In each plate is a curved sawcut82, made by the saw in themanner presently described. Plates 29 all havethe same contourand thickness, and the only difference between them isin the curvature of their re spective saw-cuts 32.

In the bottom of the aforesaid rectangular casting 15 is a longitudinalslot 33 through which projects the upper endof the pivotbolt 8 when thecarrier is in operative position. Secured to one side-of casting ,15 isa rack 34, the teeth of which are sharp and substantiallyrectangularandare directed toward the slot 33.

35 is a triangular block, the a 6r which is adapted to fit between anytwo teeth of the rack 34. In block 35 is a vertical perforation adaptedto fit, but not tightly, over the upper end of the pivot-bolt 8.

Secured beneath the corners of the table are two stops 36 for limitingthe movement of the carrier, and hence the length of the cut made by thesaw. Each said stop has an upwardly-projecting portion, as shown in Fig.7, which is struck by the carrier at the beginning or end of afull-length cutting stroke. In each stop is a slot 37, through which andthe table passes a bolt 38. Thus the stops are adjustable for cuts ofdifferent lengths. Said stops may be longerproportionately than shown inthe drawings.

The operation of the attachment is as follows: The arm 4 is secured tothe table with bolts 6. The radius of curvature of the first cut to bemade is determined and the pivotbolt 8 is set with its center at thatdistance from the saw 3. Wing'n ut 14 is tightened up to hold thepivot-bolt immovable. The carrier is laid on the table with the slot 33of casting 15 over the pivot-bolt 8. The gate 27 is opened, and a plate29, having a saw-cut 32, which will register with the cut to be made inthe stock, is placed in the carrier. The carrier is swung around to theleft to permit the saw to enter the cut 32, and the gate 27 is closedand latched. The triangular block 35 is slipped on the upper end of thepivot-bolt 8, and the point of the block will fit between two teeth ofthe rack 34 as the cut 32 in plate 29 has previously been made by usingthe carrier pivoted by means of this block. The carrier is now providedwith a fixed center of rotation or oscillation. The carrier is turnedtill the saw is at one end of the cut 32 and the piece of stock to becut is placed against the inner ends of the guides 23 and held therewith one hand, while the carrier is turned by the other hand on knob 31,either pushing or pulling the stock against the saw until the cut ismade. The first cut is preferably for the outer curve of the felly,cant, or whatever the piece may be intended for. The small piece cutaway by the saw is removed from the carrier and the curved edge of thestock is placed against the guides 23 and held there while the inner cutis made, said guides having previously been set at a distance from thesaw-cut 32 equal to the desired width of the finished piece. After thissecond cut the piece would appear as shown in full lines in Fig. 5. Thesecond (inner) out being of the same radius as that of the first (outer)cut, and the piece would be thicker in the middle than at its ends, asshown. So a finishing cut must be made parallel to the outer cut. Tomake the finishing cut correctly, the block 35 is removed from thepivotbolt 8 and the pivot-bolt is moved in toward the saw until itsdistance from the saw equals the radius of the desired finishing cut.This must be done Without moving the carrier. Plate 2!) is removed fromthe carrier and another plate having a saw-cut of shorter radius isplaced in its stead. Then the block 35 is replaced on the pivot-bolt andpushed down to engage the teeth of the rack 34. Then the piece beingheld against the guides 23 the finishing cutis made, which takes out athin crescent-shaped piece from the inner side and leaves the felly,cant, or other piece the correct shape. In cutting a number of felliesor the like the first and second cuts of all of them are made before anyof the finishing cuts are made. The purpose of this is to save the timewhich would be required for adjusting the pivot-bolt and changing plates29 for each piece.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent of the United States, is-

1. In a device for the purpose set forth, a sector-shaped frame forcarrying the stock, a hinged gate mounted at one side of said frame, anda segmental plate, adapted to be carried by said frame, for supportingthe stock, the material of said plate being soft enough to be penetratedby the saw; substantially as described.

2. In a device for the purpose set forth, a sector-shaped frame forcarrying the stock, a segmental plate, adapted to be carried by saidframe, for supporting the stock, the material of said plate being softenough to be penetrated by the saw, curved guides, forming a curvedslot, secured to the curved periphery of said frame, bolts passingthrough said slots, and guide-pieces 23 held by said bolts against saidcurved guides; substantially as described.

3. In a device for the purpose set forth, the combination with asaw-table of a longitudinally-slotted arm adapted to be secured to thetable, a sector-shaped frame for carrying the stock, a slotted castingsecured to the converging sides of said frame, a pivot-bolt dependingthrough the slot in said arm and having a portion projecting upwardlythrough the slot in said casting, a rack having inwardly-pointed teethsecured to one side of said casting, and a block having a perforationtherein adapted to receive the upper end of said pivot-bolt and a pointadapted to enter between any two of said teeth; substantially asdescribed.

In testimony whereof I affix my signature in the presence of twoWitnesses.
